Guide runner in the tightening device of this belt wheel on belt wheel support plate is straight to be offered, and its length is the displacement range that synchronous pulley can be adjusted.While needing dismounting and change Timing Belt, drive positioner along guide runner, to move the position of axis, the position that makes synchronous pulley shifts near so that lax Timing Belt, and then is beneficial to Timing Belt and easily takes off and do not pull damage.While needing normal tensioning running, according to required degree of tension, drive positioner along guide runner, to move the position of axis, make the position of synchronous pulley move far away to strain Timing Belt, and then reach the required tensioning degree of running.

In the tightening device of above-mentioned belt wheel, described positioner comprises the positioning screw rod wearing into above-mentioned guide runner along straight, and described positioning screw rod runs through the slide block of above-mentioned middle shaft end, and slide block forms and is threaded with positioning screw rod.

In the tightening device of above-mentioned belt wheel, described positioning screw rod tail end is hanging shape and stretches in above-mentioned guide runner, and it is outside that its spiral shell head is exposed to above-mentioned guide runner, and described positioning screw rod exposes the sheathed lock-bit nut of screw thread on the outside of guide runner.

Transpose when operation, first screw lock-bit nut make its with the end wall pine of belt wheel support plate from, then rotate spiral shell head and drive bolt rotary, and then by screw thread, pass the slide block being socketed on screw rod, level of synchronization movement synchronous belt is taken turns; When reaching required correct position, stop spiral shell head to screw, then screw lock-bit nut, make its outer end of being close to guide runner, to form fastening locking.

In the tightening device of above-mentioned belt wheel, on the border of described synchronous pulley two sides, install Timing Belt back-up ring.The edge of Timing Belt back-up ring exceeds the outer border of synchronous pulley, plays thus gear and establishes the effect that Timing Belt departs from synchronous pulley in transmission.

In the tightening device of above-mentioned belt wheel, sheathed bearing on described axis, described synchronous pulley is placed on above-mentioned bearing periphery admittedly.This bearing is specially ball bearing of main shaft, by bearing, realizes the smooth and easy rotation of synchronous pulley on axis.

In the tightening device of above-mentioned belt wheel, between the periphery of described bearing and the inner ring of synchronous pulley, by inlay card hole, with back-up ring, form and be connected.

In the tightening device of above-mentioned belt wheel, the both sides of described bearing are sheathed cushion cover on axis all, and described cushion cover is resisted against between the side and belt wheel support plate of bearing.Establish on the top that is symmetrical cushion cover by both sides, determines that thus bearing is in center position, and ensured the smooth running of synchronous pulley rotation.

Compared with prior art, the tensioning device structure of this belt wheel is simple, practical reliable and easy to operate, both can grow distance adjustment, also fine-tuning, both the needs of replacing Timing Belt for convenience detach in use procedure had been met, the needs of Timing Belt tensioning while having met again normal operation; Guarantee Timing Belt smooth running simultaneously, realize immediately and regulating, without shutdown, without speciality tool.

The specific embodiment

Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

As shown in Figure 1,2 and 3, the tightening device of this belt wheel comprises synchronous pulley 1, axis 2, belt wheel support plate 3 and positioner etc.

Sheathed bearing 7 on axis 2, this bearing 7 is specially ball bearing of main shaft, and synchronous pulley 1 is placed on the periphery of bearing 7 admittedly, and specifically by inlay card hole, with back-up ring 8, is formed and be connected between the periphery of bearing 7 and the inner ring of synchronous pulley 1.On the border of synchronous pulley 1 two sides, install Timing Belt back-up ring 6, the edge of this Timing Belt back-up ring 6 exceeds the outer border of synchronous pulley 1, plays thus gear and establishes the effect that Timing Belt departs from synchronous pulley 1 in transmission.

The place, two ends of axis 2 is symmetrical set belt wheel support plate 3, on this belt wheel support plate 3, offer the guide runner that is straight, the two ends of axis 2 cut into flats slide block 2a, this slide block 2a embeds the sliding block joint that forms free-running fit in guide runner, and the length of guide runner is the displacement range that slide block 2a can adjust thus.Two sides of bearing 7 are sheathed cushion cover 9 on axis 2 all, and this cushion cover 9 is resisted against between the side and belt wheel support plate 3 of bearing 7.Establish on the top that is symmetrical cushion cover 9 by both sides, determines that thus bearing 7 is in center position, and ensured the smooth running of synchronous pulley 1 rotation.

Positioner comprises the positioning screw rod 4 that wears guide runner on belt wheel support plate 3 along straight, be specially positioning screw rod 4 tail ends by outside, guide runner one end directly to penetrating, and its tail end is hanging shape in guide runner; Positioning screw rod 4 spiral shell heads are exposed to guide runner outside, and positioning screw rod 4 exposes the sheathed lock-bit nut 5 of screw thread in the outer segments of guide runner.Positioning screw rod 4 runs through sliding by tail end and is embedded the slide block 2a that is placed in guide runner, and slide block 2a forms and is threaded with positioning screw rod 4.

While carrying out tensioning positioning operation, first screw the lock-bit nut 5 on both sides positioning screw rod 4, make two lock-bit nuts 5 all corresponding and belt wheel support plate 3 end wall pine from, the spiral shell head that then simultaneously rotates both sides positioning screw rod 4 drives two screw rods synchronously to rotate, and then by screw thread, pass the slide block 2a being socketed on two screw rods, make axis 2 flat to driving synchronous pulley 1 to move distant positions to strain Timing Belt, until reach desired degree of tension, while reaching required correct position, stop screwing two spiral shell heads simultaneously, then screw two lock-bit nuts 5, make its correspondence be close to the outer end of guide runner, to form fastening locking.

While needing dismounting and change Timing Belt, screw equally and unclamp two lock-bit nuts 5, oppositely screw the spiral shell head of both sides positioning screw rod 4 simultaneously, driving axis 2 is flat shifts near position so that lax Timing Belt to drive synchronous pulley 1, and then be beneficial to Timing Belt and easily take off, and do not pull damage.

Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.

Although more used synchronous pulley 1 herein; Axis 2; Slide block 2a; Belt wheel support plate 3; Positioning screw rod 4; Lock-bit nut 5; Timing Belt back-up ring 6; Bearing 7; Back-up ring 8 for hole; Cushion cover 9 terms such as grade, but do not get rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
